The one word Kate Middleton's children's nanny isn't allowed to say in front of them

Kate Middleton's children's nanny Maria Borrallo won't be joining the family when they move to Adelaide Cottage.

• The Cambridge family nanny Maria Borallo trained at the famous Norland College, where she was taught not to call children by a certain word under any circumstances. 
• Reportedly, it's not the only thing that's banned in the Cambridge household, with another golden rule that should be adhered to at all times.

Kate Middleton's children's nanny reportedly has a great relationship with the Cambridge family, but has to follow some strict rules when looking after the youngsters. 

Nanny Maria was trained at the prestigious Norland College and has been with the family since George was just a few months old.

According to research from author, Louise Heren, who spent time at Norland College researching for a documentary, students are taught to not say the word 'kids' in front of youngsters, instead referring to children by their names, or simply as 'children'.

Louise told The Mirror, "The word kid is banned. It's a mark of respect for the children as individuals."

While Maria reportedly keeps to this rule, it's important to remember that this is a rule that was set by Norland College, and not by the Cambridges themselves.

And that's not the only strict rule that the nanny need to follow, but this one is reportedly set by Prince William and Kate Middleton themselves.

A source told The Sun, "Shouting is absolutely ‘off limits’ for the children and any hint of shouting at each other is dealt with by removal."

Maria won't be joining the Cambridge family in their new home in Berkshire, simply due to the space factor. Adelaide Cottage has just four bedrooms; one for Prince William and Kate Middleton and a bedroom each for the children, so there's no space for any live-in staff.

This will be the first time Prince George, Princess Charlotte and Prince Louis won't have a live-in nanny in their lives.
